协调控制系统在紧凑型电站仿真机上的实现

Implementation of Coordinated Control System in Compact Power Plant Simulator

该文以开发基于DCS的紧凑型电站仿真机为背景,介绍了单元机组协调控制系统在仿真机上的实现。文中采用模块化建模的方法,对每个实际的控制环节建立其仿真模型;并利用开发的模块库,采用直接能量平衡策略,完成了协调控制系统的组态,使其能仿真单元机组机跟炉、炉跟机、机炉协调、手动以及定压、滑压等运行方式,并能协调地对锅炉和汽轮机进行控制。

As a part of compact simulator for power plant based on Distributed Control System (DCS), the paper focuses on the design and implementation of the model of Coordinated Control System (CCS) in the simulator. By using modular modeling method, the model of real control component is constructed. Then the simulate model of CCS is configurated by the models through the advanced Direct Energy Balance (DEB) control strategy. Experiment results show that the simulate model of CCS can simulate different running patterns such as turbine following boiler pattern, boiler following turbine pattern, CCS pattern, etc.
